KNOCKDOWN UMBRELLA.

Specification of Letters Patent.

Patented Nov. 1'7, 1914.

Application filed August 12, 1912. Serial No. 714,628.

To all whom it may concern Be it known that I, NICHOLAS Hnrrz, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Knockdown Umbrellas, of which the following is a specification.

It is the object of my invention to provide a knockdown umbrella, the cover portion of which is arranged to fold with a plurality of cross-sectionally overlying folds so as to reduce the normal lengths of the ribs, and to arrange said folded cover portion along the median portion of the stick of the umbrella, both the ends of the stick being arranged to be detached for shortening said stick, the detached portions of the stick being capable of attachment alongside of the folded portion for forming a compact and short package.

The invention will be readily understood from the following description and claim, and from the drawings, in which latter:

Figure 1 represents an umbrella embodying my invention, partly broken away, and shown in spread relation. Fig. 2 is a side elevation of my improved device showing the umbrella in partly collapsed relation. a portion of the covering and part of the ribs being removed for better illustration of the parts. Fig. 3 is a similar view, showing the parts in collapsed relation, with the upper and handle sections of the stick removed. Fig. 4 is a side elevation of my improved device in completed knockdown relation. Fig. 5 is a longitudinal axial section, partly broken away. illustrating the pivotal con nections and hinges and take-apart portions of my improved device. Fig. 6 is a bottom view of a detail partly in section and partly broken away, showing the rib-sleeve and one of the ribs pivoted thereon; and, Fig. 7 is a detail in side elevation showing the connection between the brace-sleeve and the ribsleeve.

11 represents the stick of my improved device, which comprises a median section 12, an upper section 13, and a handle section 14. These sections are arranged to be connected and disconnected preferably by means of screw joints 15, 16.

17 represents the brace-sleeve, forming a slide, with which a catch 18 cooperates when the umbrella is in closed relation, the catch 18 being received in a slot 19 of the sleeve. The sleeve 1? has the braces 20 pivoted thereon in a usual manner as at 21. A catch 22 cotiperatcs with said brace-sleeve when the umbrella is in open relation, said catch being then received under said sleeve.

25 is a ribsleeve which forms a slide, and is normally located at the upper portion of the stick. The rib-slceve has the ribs 96 pivoted thereon in a usual manner, as at 27. The braces are pivoted to the ribs at 28.

Each of the ribs has a hinge 31 therein be tween the rib-sleeve and the pivot 28, and a hinge 32 therein between the pivot 28 and the outer end of the rib, for forming inner rib-sections 33, median rib-sections 34, and outer rib-sections 35. The hinges 31 and 32 hinge in opposite directions when the umbrella is collapsed. The rib-sleeve 25 also has releasable connection with the upper section of the stick, instanced as a catch 37 received in a slot 38 in said sleeve, the upper end of the sleeve being received against a collar 39 secured to the upper section of the stick.

There is a releasable connection 40 between the sleeves, this connection be-ing arranged to be released when the umbrella is in use as an umbrella and arranged to be connected for drawing the rib-sleeve with the brace-sleeve in the knockdown movement of the umbrella. I have shown this connec tion as a tube 41 which has threaded connection 42 with the brace-slcevc. The tube has hooks 43 at its upper end received in an annular slot 44 in the lower end of the ribsleeve through recesses 45 in the lower wall of said slot. \Vhen the hooks are in said slot the rib-sleeve and brace-sleeve are connected for combined movement, and when said hooks are in line with said reces es said brace-sleeve has movement indepemlcnl of said ribsleeve. The catches 18, 22 and 37. are spring catches of the usual construction employed in umbrellas. the catches 1S and 22 being oppositely disposed on the median section of the stick, the catch 15 having its holding face presented downwardly and the catch 22 having its holding face presented upwardly. The catch 37 is located on the upper section of the stick.

The median and outer sections of the ribs are preferably U-shapcd in, cross section, the nine sections thereo'l" being preferahl narrow in cross-section for being rel-rived partway in the channels of said nu'dlan 14cctions, and the links aid of the hinges are also preferably narrow in cros LlfLitlU-l. for

swinging readily in the channels of said median and outer sections of said ribs. Thimbles 47 are received across the hinges 31 and thimbles 48 are received across the hinges 32 for stifiening the same when the umbrella is in use as an umbrella. The central portion of the cover 52 is fastened to the ribsleeve, as shown at 53, and moves with said rib-sleeve. The outer edges of the cover are fastened, as shown at 54:, to theouter ends of the ribs.

When it is desired to collapse the umbrella, the umbrella having been first opened for causing the hooks 4:3 to pass through the recesses 45, the tube 41 is turned for moving its hooks 43 into the anuular slot .44: so as to-placesaid hooks above the lower wall of said slot, thereby conmeeting the sleeves. The catches 22 and 37 being released, pulling the brace-sleeve 17 downwardly will draw the rib-sleeve 25 with it. The lower inner face of the ribsleeve is beveled as shown at 55 to readily pass the catch 22. The inner ends of the inner sections of the ribs and the central portion of the cover are thereby drawn toward the handle and the hinges 31 moved toward the stick. In this movement the inner sections of the ribs and the braces are of the ribs are thereby laid lengthwise of i the median section of the stick, with the inner stretch 56 of the cover between said stick and inner sections of the ribs. The said inner sections and median sections of the ribs and the braces are by the same movement laid between the inner stretch 56 and the median stretch 57 of the cover. The hinges 31 are preferably nearer to the pivots 28 than to the pivots 27, so as to shorten the ultimate length of the knocked down um-- brella. The outer sections 35 of the ribs are swung upon their hinges 32 for laying said outer sections lengthwise of the stick, with the median stretch 57 and the outer stretch 58 of the cover between the median and outer sections of the ribs. When the ribs, braces and cover of the umbrella have been collapsed, the upper and handle sections of the stick are released from the median section of the stick, and placed alongside of said median section of the collapsed umbrella, whereupon the collapsed portions will be suitably secured together, as by straps 59.

Having thus fully describedmy invention, What I claim asnew and desire to secure by Letters Patent, is: i

In an umbrella, the combination with the stick, of a rib-sleeve and a brace-sleeve, each of said sleeves having slidable connection with said stick, and a tube received about said stick between said sleeves, the lower end of said tube having threaded connection with said brace-sleeve and rotatable on said brace-sleeve, the upper endof said tube profvided with hooks, said rib-sleeve provided with an annular slot-in'its lower end, the lower wall of said slot provided with recesses therethrough, said brace-sleeve and tube arranged for movement lengthwise of said stick independent of said rib-sleeve during which said hooks move through said recesses, and said hooks arranged by rotary movement thereof to be received in said annular slot above said lowerwall for connecting sa1d sleeves for comblned movement, substantially as described.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
